Getting off the media reservation and reading conservative news sources is something we postliberals do, er, have done. Which comes first? Does reading/watching/hearing conservative sources as opposed to the standard liberal ones create the change fairly automatically by reflecting reality better, or do you have to already get it to a certain extent to read New Media without your head exploding?
If the former, we might do better to simply challenge people to read other sources rather than attempting to argue with them.
It's sort of like the idea that wags had about bringing down the USSR by dropping planeloads of Sears Catalogues on them; or more seriously, the Bible distributors who work to simply get Bibles into a country to work on their own even if no missionaries are there.
